Value Collection CPM-12 Wheel Mandrel 3/16 in Hole

Product Description

The VALUE COLLECTION CPM-12 is a wheel mandrel designed to mount abrasive or polishing wheels onto rotary tools, die grinders, and similar power equipment. It accepts wheels with a 3/16 inch hole and features a 1/4 inch shank diameter for secure chuck engagement. The mandrel measures 1-3/4 inches in overall length and accommodates wheels up to 1 inch in maximum width. The 1/2 inch head and washer diameter provides even clamping pressure across the wheel face. This type of accessory is commonly installed by machinists, fabricators, and maintenance technicians performing grinding, deburring, or surface finishing work.

This wheel mandrel is suited for use with small abrasive or buffing wheels in bench-top and handheld rotary tool applications. It fits standard 1/4 inch collets and chucks found on die grinders and rotary tools used in light fabrication, tool and die, and general maintenance environments. The compact overall length and narrow wheel width capacity make it well suited for detail work in confined areas or on smaller workpieces.
